A small $20 splurge here and there feels like exactly that: a small splurge. While that can be true, it can also become a financial trap. That’s because $20 spent a few times a month doesn’t add up to much, but spent several times a month can add up to too much.

Here's why small expenditures can wreck your financial goals far more severely than a few big buys.

Think of it like this: Let’s assume you visit Starbucks on the way to work roughly twice a week, spending $10 each time on a coffee and a pastry. Also assume you spend $40 total on home entertainment streaming services, and you order from a food delivery service like DoorDash or Uber Eats once a week and spend $25 each time. On top of that, you likely make a number of small impulse buys per week – a fast-food run once or twice a week at $20 a pop, or perhaps two $20 movie tickets per month. Finally, like most people, you probably buy something small on Amazon a few times per month for $20 or less, because what’s $20 going to hurt?

The answer to that question is simple: $20 can hurt a lot when you add up all those charges over the course of a month. Take a look at how those very normal, everyday expenditures can add up across 30 days:

  • Starbucks: $80

  • Streaming services: $40

  • Food delivery: $100

  • Fast food: $80

  • Movie tickets: $40

  • Amazon: $60

  • Total: $400 per month.

That is the definition of the $20 trap: the way in which small spends over the course of a month can eradicate the entire “fun expenses” section of your monthly budget without you even realizing it, because each spend feels so tiny in the moment.

“Small purchases usually don’t wreck your goals because they’re large,” Vinay Metharamani, financial expert at Delancey Street, told MoneyLion. “They wreck your goals because they’re repetitive, frictionless and easy to justify. Nobody feels alarmed by a $14 lunch, a $19 streaming charge or a $17 impulse buy. But when those expenses repeat across a month, they stop being minor and start acting like a second bill.”

As Metharamani explained, the problem is that people view these purchases as “one at a time” events, whereas finances actually happen in “totals.” Your regular Starbucks order shouldn’t be viewed as a singular event. If you go often enough to have a “regular” order, that means you essentially have a monthly Starbucks bill with a total far higher than just $10 or $20.

“What makes the $20 trap so dangerous is that it often lives on autopilot. Subscriptions renew quietly,” Metharamani said. “Convenience spending shows up when people are tired. Impulse buys happen because the checkout process is now almost effortless. The spending doesn’t feel serious in the moment, but the monthly total is very serious once you finally see it in one place.”

The existence of a $20 trap doesn’t mean you should stop treating yourself to small purchases here and there. It’s important to live your life and splurge responsibly now and then.

“The best way to combat this is not guilt,” Metharamani said. “It’s visibility.”

What’s the best way to maintain that guilt-free financial visibility then? Metharamani recommended a “small-spend audit.” For 30 days, catalogue every transaction under $25.

“Don’t guess. Don’t estimate. Add them up. That exercise changes behavior fast because it turns vague spending into a hard number,” he explained. “Once someone sees they spend $427 on convenience and impulse purchases in one month, the conversation becomes very different.”

If you want an added layer of security against the $20 trap, consider adding what Metharamani called “friction” back into your spending. He advised deleting saved cards from delivery apps, canceling unused subscriptions and pausing nonessential purchases for 24 hours.

“The goal is not to make life miserable,” he said. “The goal is to slow down a decision that has become too automatic.”

By recognizing just how much you spend in $20 increments across an entire month (and slowing down how easy it is to make those purchases), you can literally save yourself hundreds monthly and redirect those savings back to your larger financial goals.
